Hurricanes Helene and Milton Further Proof We’re Not Ready for Fossil Fuel-Caused Climate Change  

Union of Concerned Scientists

In August, the National Oceanic and Atmospheric Administration (NOAA) issued its updated forecast for the 2024 hurricane season. Significantly warmer than usual surface temperatures in the Atlantic Ocean, which come largely as a result of human-caused climate change. Why are the oceans so warm and fueling this rapid intensification?

The water south of Greenland has been cooling, so what causes that?

Real Climate

Here we start by taking the Greenland mass loss rate into the ocean, times the temperature difference between the meltwater and the water it replaces. For the part entering the ocean as ice, we must also consider that to melt ice requires energy. Greenland ice melt. or other estimates). References. Trenberth, K. & Fasullo, J.

Manabe’s subsequent work led to the development of the GFDL GCM, initially just including the atmosphere, but eventually with an ocean, and then the transient results shown in Manabe and Stouffer (1993). The basic issue stems from the different timescales of the ocean and atmosphere. 1975) , and Bryan et al.

Back to basics

Real Climate

It’s an arresting graphic, and follows in from the record high ocean surface temperatures that were being reported a month ago. Since the seasonal cycle over land is much larger than over the ocean (smaller heat capacity, and less evaporation), that means that the seasonal variations in the north outweigh the variations in the south.

However, on the level of basic physical reasoning, it is of course a no-brainer that warming will cause land-ice to melt (and melt faster as it gets hotter) and ocean waters to expand, so sea-level rise is the inevitable result. meters of rise by 2100. The Long Term Future.
